Christian Mauderer 0b30f38951 ipsec-tools: Reduce allocated buffer size
By default, pfkey allocates a 2MB buffer that is used for SPD entries.
This size is a good choice for a server system where a lot of clients
should be handled. But on our embedded systems, an application with that
much clients is unlikely and 2MB is a lot of space. So reduce that to
the default value of 128kB which should be enough for a small number of
ipsec connections.

See https://bugzilla.redhat.com/show_bug.cgi?id=607361 for more details
why the upstream project originally increased the size.

If someone really needs a bigger size, there is a option in the
configuration file of pfkey called `pfkey_buffer` that can overwrite
this value.

Closes #4621

IPsec-tools
===========

This package provides a way to use the native IPsec functionality 
in the Linux 2.6+ kernel. It works as well on NetBSD and FreeBSD.

	- libipsec, a PF_KEYv2 library
	- setkey, a tool to directly manipulate policies and SAs
	- racoon, an IKEv1 keying daemon

IPsec-tools were ported to Linux from the KAME project 
(http://www.kame.net) by Derek Atkins  <derek@ihtfp.com>.

Currently the package is actively maintained and developed by: 
	Emmanuel Dreyfus <manu@netbsd.org>
	VANHULLEBUS Yvan <vanhu@free.fr>
	Matthew Grooms <mgrooms@shrew.net>
	Timo Teräs <timo.teras@iki.fi>

Sources can be found at the IPsec-Tools home page at:
	http://ipsec-tools.sourceforge.net/

And CVS repository is hosted at NetBSD tree:
	cvs -danoncvs@anoncvs.netbsd.org:/cvsroot co ipsec-tools

Bug reports and project wiki is located at:
	https://trac.ipsec-tools.net/
